  • Automatic transmission

ABS activation at low speed and then ABS holding up. I almost got into 3 accidents with small children in car. I have replaced brake pads, rotors, ABS sensors, calipers, brake lines and brake switch. Nothing works. Front tire area catches on fire if driven for long distances. Hard time stopping. GM will not recall or repair. There is a tsb (020525006) on same problem but not for my state. Recall in other parts of country for same problem, but GM states not for my state even though it is for same problem. Very dangerous to drive.

Last week it was cold & snowing. I was coming to a stop sign at a very low speed. I attempted to brake, the vehicle did not. I proceeded through the stop sign and struck another vehicle. Again today I was approaching a stop sign when I attempted to brake, the vehicle did not stop. Today there was luckily no on coming traffic. I will be taking my vehicle in for inspection.

The contact owns a 2004 Chevrolet Trailblazer. The vehicle has been to the dealership about 4 or 5 times for the brake system. When a diagnostic test was performed on the vehicle it did not indicate that there was a brake problem.. when the brakes were applied the pedal went to the floor, the vehicle would slow down, but will not stop. No warning lights illuminated, indicating that there was a problem with the brakes. This did not happen every time that the brakes were applied. The weather condition has no impact on the braking capability. The manufacturer stated that if the diagnostic test showed there was nothing wrong then there was nothing that they could do about the problem.

My daughter was driving my 2004 Trailblazer on an icy, slippery road at 25 -30 miles per hour, (the speed limit is 30, it was the street we live on) when she lost control, hit a tree and totaled ($22,000) the vehicle. The officer and I walked the path in the street and could not find any signs of skidding or braking, there fore leading me to believe now that there was a braking failure. Up until now, when I heard about the brakes failing do to corrosion from road salt, I always thought it was just an accident in poor road conditions. When I first read the report of the investigation I couldn't belive it was the same scenario as her accident. Poor road conditions, therefore possible salt buildup, a slow speed and inability to stop. I am so gratefull that she walked away without a scratch, also considering the air bags did not deploy, even though the front end was totaled. I am sure this is a problem that must be identified for those living in colder, northern states.
